Calorimetry

We possess several different calorimeters based on different principles and covvering different temperature ranges.

For measureemnts of heat capacities, the lowest uncertainty (less than 1 percent) can be achieved with calorimeters of Tian-Calvet type (older SETARAM microDSC IIIa and its successor SETARAM microCalvet), which however operate in a limited temperature range 230 K to 350 K.
This temperature range can be extended using power-compensation DSC (PerkinElmer 8500) and relaxation caporimeter Quantum Design PPMS (2K to 300 K)..

Another DSC (Thermal Analysis Q1000) is used for studiing phase and glass transitions, constructing phase diagrams etc. More delais are povided below.

Apparatuses for vapor pressure measurements

In 1990 we have found inspiration in static apparatus working in Lyon (prof. J. Jose, Dr. I. Mokbel, Laboratoire d'Instrumentation et de Chimie Analytique en Solution, Univ.´ Claude Bernard, 69622 Villeurbanne, France.). Later we have constructed our own apparatuses, which are fully automated and cover pressure range from ca 0.05 Pa to 10 kPa (see figure on left). Respective apparatuses are described in more details below.
